10 MPH Speed Limit for Cars and Bikes on Crystal Springs at Polhemus

This is a friendly reminder that there is a 10 mile per hour speed limit for cars and bikes near the intersection of Crystal Springs Road and Polhemus Road at the North Shaft site. This is for the safety of everyone. It is a small speed limit zone and we ask everyone to use caution in the area and follow the speed limit.
